Title: Gas turbine power plant
IPC: F02C3/13
Filed: 1966-06-20
Abstract: 1,148,578. Gas turbine engines; aerodynamic couplings. TWIN DISC Inc. June 20, 1966 [June 23, 1965], No.27396/66. Headings F1G and F1X. The invention relates to a gas turbine engine which is arranged to drive a power output shaft through an aerodynamic torque converter, the casing of the torque converter being connected to receive air tapped from the compressor discharge and to discharge air back to the working fluid circuit of the engine either upstream or downstream of the combustion equipment. The engine shown comprises a compressor 11, air preheater 17, combustion equipment 15 and turbine 12, the turbine being connected to drive the compressor through shaft 13, and the turbine and compressor shaft extension 24 being connected to drive a power output shaft 25 through an aerodynamic torque converter 20. The torque converter comprises a casing 21, an input or pump member 23 secured to the shaft 24 and an output or turbine member 25<SP>1</SP> secured to the output shaft 25. The converter casing is connected to the compressor discharge through line 26 in which are disposed a valve 28, a pump P 2  and a pressure regulator 33. The converter casing is also connected to the engine circuit either upstream (as shown) or downstream of the combustion equipment 15, through line 27 in which are disposed a valve 29 and a pressure regulator 35<SP>1</SP> which is controlled by an element 35 responsive to temperature of the air in the converter casing 21. The casing 21 is also connected to the inlet 32 of the compressor 11 through line 30 in which are disposed a valve 31 and a suction pump P 1 . The line 30 is also connected to an air ejector 36 by way of a line containing a valve 38, the pressure air for the ejector being taken from the line 26. A device 34 responsive to the temperature at the inlet to the turbine is connected to the pressure regulator 33 also to the temperature responsive element 35 to adjust the datum thereof. At starting of the engine, the converter casing would be evacuated so that no torque is transmitted to the shaft 25 - the valves 28 and 29 would be closed and valve 31 opened so that the casing 21 is connected to the compressor inlet 32. The suction pump P 1  may be used to further decrease the pressure in the casing 21, or the ejector device 36 may be used by opening the valve 38. When the engine is to supply shaft power, the valves 28, 29 are opened and valve 31 closed so that air under pressure is supplied to and discharged from the casing 21. The pressure of air supplied to the casing may be increased by means of the pump P 2  in the line 26. At idling, the valves 28, 29 are closed and the valve 31 opened as in the starting phase. A braking effect on the turbine can be achieved by partial closing of the valve 29 which results in increase of pressure of the air in the converter casing; alternatively the pressure may be increased by operating the pump P 2 .

Title: Process controllers
IPC: C23C2/18
Filed: 1973-06-11
Abstract: 1438515 Automatic control systems INDUSTRIAL NUCLEONICS CORP 11 June 1973 [9 June 1972] 27747/73 Heading G3R Set points for a plurality of parameters affecting the formation of a product are determined by a  computer in response to measurements of properties of the product, the computer separately deriving the spread in the value of each property over a predetermined time and also the deviation of the combined individual values. Controllers for the parameters are adjusted to eliminate differences between the measured values and the set points. The object is to automatically place the set points as close as possible to a limiting value, the margin being dependent upon the spread in measured values. The invention is described in respect of zinc plating both sides of a steel strip 11, the parameters being the respective thicknesses, which are controlled by the position of knives 13, 14 and measured by scanning radiation gauges 15, 16. The gauge outputs are compared with the set points at knife controllers 21, 22. To determine the set points the gauge outputs are supplied directly to computer elements 23, 24, and their sum to element 25; these elements calculate the standard deviation of the respective quantities according to a given formula, and from these the minimum allowable set points are obtained, having regard to defect limits 28 (i.e. that thickness below which the product is regarded as defective) set by an operator and also operator set "fraction defective" 27 (the percentage of product deliberately allowed to be defective, having regard to the relationship of economic production with customer satisfaction). Allowance is made for gauge noise by a unit 29, which calculates the apparent deviations due to noise alone when the strip 11 is stationary. From the outputs of elements 23 --- 25 are subtracted the actual set points used during the previous cycle (e.g. the previous scan) and the differences fed to further computer element 41; this calculates the new set point values from these three inputs, having regard to operator set-values for minimum, maximum and desired ratio of thicknesses on respective sides of the strip. It is shown by diagrams Fig. 2 (also 3 - - - 5 not shown) how computer 41 arrives at the optimum set values, having regard to both the boundary and desired conditions. Some details of the computer programme are given. Relating the above to Fig. 2, elements 23, 24 calculate deviation curves 54, 55, which are then "positioned" so that the shaded areas 56, 57 satisfy the conditions manually set at 27, 28. The mean values of 54, 55 are then the minimum thickness outputs from 23, 24, represented by lines 52, 53. Line 51 is the output of 25 for minimum total thickness (i.e. both sides together). Computer 41 then arrives at set point 74 as being the nearest to desired ratio line 71, not exceeding maximum or minimum ratio limits 72, 73 and using the minimum amount of coating material (it is on line 51) without dropping below minimum values 52, 53 for either side.

Title: Method for increasing the safety of glass-containers and  a cap for use therein
IPC: B67C3/06
Filed: 1972-06-14
Abstract: 1398013 Reducing effects of shattering; glass bottles DART INDUSTRIES Inc 14 June 1972 [15 June 1971] 27789/72 Headings B8T and B8D The violence with which a glass bottle filled with carbonated liquid will shatter is lessened by reducing the area of glass in contact with free gas, this being achieved by filling the bottle to leave only enough headspace to accommodate any expected thermal expansion of the liquid. The closure may have a space into which liquid can expand constituted by a chamber inside a stopper or by a space or chamber bounded by the top wall of a cap. Alternatively a stopper may have a resilient liquid-tight chamber which is distorted by the expanding liquid. The glass fragments may be contained by providing a shield of paper, foil, netting, fabric or plastics at least around that part of the bottle contacting free gas and extending over a portion of the bottle contacting the liquid. The glass of the bottle may also contain asbestos fibres to reduce fragmentation.

IPC: C23C8/66
Filed: 1925-11-05
Abstract: 242,978. Rheinische Metallwaarenund Maschinenfabrik. Nov. 17, 1924, [Convention date]. Case-hardening; annealing.-In a process for case-hardening steel articles for the purpose of producing glass hardness over the whole surface or parts thereof, the articles after carburization and prior to quenching are subjected to the action of a metal bath or equivalent controllable source of heat such as an electric furnace, the time of subjection to the bath &c. being determined by experiment so that, at the carburized places only, the carburized layer is raised to the hardening temperature. The heating up to hardening temperature may be effected to a depth, less than that of the carburization, to which glass hardness is to be produced at the carburized places. The bath used may be of molten lead or other metal, and the parts of the surface which are to be left uncarburized may be covered by protective material. The articles may be 'hardened and tempered before being heated to the hardening temperature, or may be heated to a temperature below that which would modify the structure of the material of which the articles are composed.

Abstract: 902,166. Ion sources. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug. 16, 1960 [Aug. 17, 1959], No. 28023/59. Class 39 (1). In a molecular beam ion source for use in a mass spectrometer in which a gaseous sample, e.g. uranium hexafluoride, is introduced into the source 3 through an orifice 23 by means of a pipe 4, the bore of the pipe is smaller than the orifice so that substantially all of the sample passes directly from the pipe through the orifice and the pipe is spaced from and hence thermally separated from the ion source. Hence corrosion in the region of the ion source and isotopic exchange memory effects are reduced. The discharge end 9 of the pipe may be formed of ceramic material. The other end 5 of the pipe is close to the endplate 2 of the ion source compartment in order to reduce the length of the pipe and so reduce adsorption memory effects. The electron beam 25 for ionizing the gaseous sample is projected through a channel defined by two apertured plates 19. Suitable dimensions are given. Specification 874,833 is referred to.

A transmission line transformer passing a wide band of frequencies comprises n-l bifilar line sections wound on the same core wherein n represents the maximum voltage transformation ratio, said sections having the same number of turns and being connected so that the input voltage of any section is added in phase to the output voltage of the same section, and the output voltage of each section is applied as the input voltage of the next section, the possible transformation ratios being r : s where r and s are whole numbers between 1 and n. Fig. 4 represents a transformer having four bifilar line sections wound on a core N. If a voltage E1 is applied between terminals 1 and 2 then a voltage of 2E1 is obtainable from terminals 1 and 4. Ratios 1 : 3, 1 : 4, up to a maximum ratio 1 : 5 are available if output is obtained between terminals 1 and 8, 1 and 12, 1 and 16 respectively. Many other transformation ratios are available depending on which terminals the signal voltage is applied to or the output tapped from. For example, if a voltage is applied to terminals 1 and 4, or between 1 and 8, or between 1 and 12 and the output taken from terminals 1 and 16 then ratios 2 : 5, 3 : 5, 4 : 5 are obtainable. Ratios 2 : 3 and 3 : 4 can be obtained if the input terminals are respectively 1 and 4, 1 and 8. The above voltage ratios apply only if the transformer is matched and if the whole winding is short compared with the wavelength of E1.
